Why do you have to know the circumference of your bicycles wheel in order to set a cyclometer?
A larger diameter wheel rotates a fewer number of times to cover the same distance as a smaller wheel.
If a circle with a diameter of 4 inches rotates 1000 what distance will any one spot on its edge actually travel?
1 revolution = 1 circumference = (4 pi) inches1,000 revolutions = 1,000 circumferences = (4,000 pi) inches =12,566.4 inches (rounded)1 furlong 129 yards 2.37 inches (rounded)
Does a segment have a line of symmetry?
actually it does b/c its so cool it rotates the line
What are all circles?
All circles are plane curves drawn by a point that rotates 360 degrees at a constant distance from a fixed point.
If a circle with a diameter of 4 inches rotates 100 degrees what distance will any one spot on its edge actually travel?
There are a couple of ways to look at this problem, so the wording is very important. The question you ask is the distance actually traveled, which is measured along the outside of the circle. Because the circle turns 100 degrees, or 100/360 of a full rotation, and the circumference is 4*pi, this distance is (100/360)*(4*pi) = 3.49 inches (approx) You can also ask what the displacement of the point is, which is the straight-line distance from its starting point to the ending point and is measured along the chord drawn between the points. This distance is the base of an isosceles triangle with equal sides of length 2 inches and an angle of 100 degrees between them. One way to calculate that length is to apply the law of sines (and note that the remaining two interior angles have measure 40 degrees): base = (2 / sin 40) * sin 100 = 3.06 inches (approx)
How many speed settings are on this Wall mount fan?
There are three speed settings for this fan and it rotates 90 degress.

Are all stars the same distance from earth explain?
Well, they clearly aren't for closer stars, astronomers measure the angle the star's light hits the Earth at 6 month intervals - as the Earth rotates around the sun at a known distance, it's simple geometry given the two angles and the diameter of the Earth's orbit to calculate the distance of the star in question and the distance varies.
What is the distance covered by the earth on its axis when it rotates?
Its own circumference perpendicular to its axis
If a circle with a diameter of 4 inches rotates 1000 degrees what distance will any one spot on its edge actually travel?
Each full rotation of the circle equates to 360°. When the circle has rotated through 1000° it has rotated 1000/360 = 2.7778 times. Each rotation means that a spot on the perimeter travels a distance of 2πr = πD inches. A rotation of 1000° means the spot has travelled 2.7778 x 4π = 34.91 inches (2dp)
How do you know that the sun does not move at all?
The sun actually rotates so it does move.
What is the only planet in your solar system that rotates different direction than any other planets?
That would be Venus which rotates retrograde. Actually, Uranus does too.
How does Saturn spins?
It spins around a fixed axis once every 10 hrs 14 min, which is fast enough to make the equatorial diameter 9.8% large than the polar diameter.

Which one of these do not move Sun Moon Earth?
Actually all moves. The sun rotates on its axis. The earth rotates on its axis and revolves around the Sun. The moon revolves around the earth
What is the only planet that rotates a different direction than the other planets?
Actually there are two, Venus and Uranus.
